What is Junction Box? What is it for? Where to use?

Used as the connection point of electrical cables and conductive materials in areas such as construction sites and construction sites, the junction box is a box-shaped material with 2 or 4 outlets. The junction box used for security purposes ensures safe and orderly use of electrical connections that could compromise security if left exposed.

In this content, we will talk in detail about the answers to the most frequently asked questions about junction boxes, such as what is a junction box, what does a junction box mean, what is it used for, what are its types, in which areas is it used, what kind of features does it have and what are its features.

What is Junction Box?

When we look again in detail at what is junction box, we see that it is a word of French origin and is derived from the word 'box'. This box provides internet, telephone, electricity, etc. It serves to combine the cables of any different connection networks at a single point without getting mixed up or damaged.

What is the Use of Junction Box?

It is a type of box in which the connections used or to be used in a structure containing line cables or conductive wires such as electricity, internet and telephone are combined into a single main connection. When this box is opened, you will see that all connections are connected to different areas without interfering with each other. It prevents potentially dangerous connections from being exposed when a large number of installations are required to be combined, and ensures work and environment safety.

Against the risks that an active line connection may pose, it is necessary to prevent external deteriorations in the operation of the installation and to protect people, animals, the environment, etc. It is a material used to ensure security. If we were to summarize the benefits it provides in items:

1-) Protection of connections in an installation

2-) Ensuring secure management and control of connections in an installation from a single point

3-) Ensuring that the connection points are hidden aesthetically

4-) Reducing the risk of electrical fire

5-) Human, animal etc. When contact with installation connections that may be dangerous to living beings is desired, we can state that it is possible to completely cut it off to the outside with the junction box cover.

Where is Junction Box Used?

Electrical installation, internet line, telephone line, etc. Junction boxes are used wherever there are cables or conductors of more than one different installation. Separating these lines from each other, ensuring that control points are hidden and protected, etc. Junction boxes are used in all kinds of installations where there are demands and security must be ensured.

Junction Box Types

Let's specify the junction box types as follows:

1-) Tunnel junction box

2-) Square junction box

3-) Surface mounted junction box

4-) Norm junction box

5-) Contact junction box

6-) Steel junction box

Junction Box Features

Let's examine the summary of the junction box types, one by one, in detail.

Tunnel Junction Box

Round-shaped tunnel junction boxes are one of the most common types today, and it is necessary to cut the head part of the tunnel junction box while making the connections. They usually have a diameter of 80 mm.

Square Junction Box

Square junction box is one of the most commonly used types and is preferred in line connections of apartment networks. Rough construction cables, construction site cables, etc. It is also very common in areas. Its dimensions can vary from 10x10 to 20x20.

Surface Mounted Junction Box

Surface-mounted junction boxes with dimensions of 20 - 50 mm are mostly seen in old buildings. Nowadays, they are used flush-mounted instead of surface-mounted.

Norm Buat

It is an effective type of junction box that can accommodate a large number of channels and can be produced in a round shape and in different sizes. These junction boxes, which generally have a diameter of 40 mm - 70 mm, are flatter than tunnel junction boxes.

Contact Junction Box

Contral junction boxes have an elliptical round shape and have a single entrance at the bottom. This type, which is approximately 80 mm long, is very frequently preferred today.

Steel Junction Box

It is a type of junction box made of reinforced cast steel and can be produced in different sizes. Since they are resistant to all conditions, they are preferred for lines and installations where extra security is required. Examples of areas where such junction boxes are used include strategic military buildings and shelters.
